My invention pertains to a building construction and the method of making it and more particularly the method of assembling building units and then associating therewith an induratable material in such a way as to interlock all of the initially distinct elements and obtain an integral mass of predetermined fabricated form.

I mention my familiarity Witlrmuch of the prior art both practiced and patented. The latter is partially evidenced by: Robinson, No. 1,150,967, of August 24,

Gamewell, No. 1,171,036, of February, 1916.

2 An object of my invention is to provide a strong, light, simple, ireproof, soundproof, insulated, sanitary'and economical structure. I reduce the cost of erection, especiallythe labor cost, by eliminatingthe need of any shoring andother temporary structures, such as molds or forms. Upon a suitable base foundation I erect walls comprising larger wall sections than heretofore generally used 3 and which are preferably hollow tiles of varying hollowed divisional shape to suit conditions. The wall sections are caused tobe stood on end in laterally adjacent arrangement and their juxtaposed edges are formed with recesses, of any desired shape, so that in conjunction with each pair a vertical duct is provided in which reinforcing elements and c later induratable material, such as concrete, may be placed. Such wall sections,'if each extends from floor to fioor and from one beam carrying column to the next, maybe more quickly assembled with fewer laborers and will gravitationally maintain their positions until after the wall has reachedits desired length, when the series of tiles 1n abutting arrangement are to be interlocked. Upon the tops of the walls I then place preformed troughs of molded material which have their 5o with the wall ducts and which have `one or b'oth side walls fashioned with apertures for the insertion of preformed beams, the ends of which project into the troughs preparatory to being appropriately interlocked therewith. 'lhe beamsare supplied along longi- 55 'tudinal sides with ledges so that .floor slabs Y faces of the t-ile elements or entirewall is not to be covered, they may be ornamented in any desired manner and those surfaces of vinitially separate wall elements, with which concrete or plaster is to come in contact, may

be roughened to improve adhesion thereto. Manifestly, my construction should be stronger, will be animal and insect proof and m will require no wood, except at doorA and window jambs or for the flooring, if desired. It will be feasible, with the aid of a crane, to have the wall elements as large as conditions warrant, say, one foot thick by four or more feet wide by nine feet high (1 X 4 X 9') in dimension.

'It is to be realized that the scope of my invention comprehends manyequivalent methods and constructions. The showing of the drawings and the particular description are merely specific exemplifications of a plurality of mechanical embodiments and arrangements.

Adverting to the drawings:

Figure 12 is perspective view of anima skeleton of a buildin `section as it wou d appear if the Walls an floor were removed.

A series of duplicate wall sections 1, as shown in Figure 1, are fashioned with staggered vertically extending openings 2.' End edges 3 of the tiles abut and middle portions therebetween are recessed at 4. As -illustrated in Figure 1, the opposed recesses 4 together define a duct or well of hexagonal cross-sectional shape, but such shape may be varied, as for instance, to be quadrangular, as indicated by the dotted lines, one of which is designated by the reference character 4. Corner sections 5 are shown Aas L shaped, though their edges are similarly recessed at 4. 1t is to be understood, that the up-ended or erect wall sections 1 are as long as it is desired that thewall shall be high and preferably so thatonly one. section is placed between each pair of beam supporting columns. The wall sections are positioned against each other in a laterally extending row, and the number of tiles in each` horizontally extending row is determined by the desired length of the particularwall. Metal reinforcing elements 6 are positioned in the vertical ducts and ultimately embedded in concrete 7 whereby to unify and interlock adjoining columns of the sections.

In Figure 2 is shown a simplified modification of tiles 8 suitable for interior walls and each including a single row of openings 9 while op osed edges of the laterally abutting tiles confine a smaller space 10. In Figure 3 is illustrated'how the sections 1v are spaced apart at preformed windows anddoor :lambs 11, the remote sides of which define a three sided recess 12 in opposition to the wall section recesses 4; the space defined by the recesses 4 and 12 being subsequently filled with concrete 13.

After any articular wall section has reached its desired length its upper surface is mortar coated and a trough 14 permanently set thereon. The troughs include side walls 15, one or both of which, depending upon whether they are placed on outer or .inner walls respectively, are provided with a series of definitely spaced apertures 16. T he bottoms 17' of the troughs are also provided with openings 18. The apertures 16 and openings 18 are preferably spaced together in pairs at the points on the wall where the vertical ducts are provided between ad-v joining stands of tiles.- Preformed bea-ms 19 are shaped to fit in the apertures 16 and reinforcing elements 20 in the beams projectv therefrom at each end where the extremities lof the elements 20 are bent to form hooks 21.

The beams are also'fashioned on opposite lon'- gitudinal sides with led es 22.

It is to be understoo that'the beams 19 will support flooringand extend across parallel .walls with their end's occupyin a pair of alined apertures 16, as shown in ig-v trated at 24 in Figure 6, thereby eventually providing a greater bearing area for the oor beam. Other reinforcing rods 25, shown in Figures 6 and 11, extend longitudinally in the troughs 14 and are .partially embraced by the hooks 21, as shown in Fi ure 6, for the pur ose of providing an ad itional interlock; luid concrete is then poured into the troughs 14 and into the vertical wall ducts until all become lled, as disclosed in Figure 11, whereby the base 26, wall columns, troughs and beams become a unitary, substantially integral mass after induration and as suggested by the imaginar trated in Figure 12, to inc ude the base 26, the concrete columns 7, .beams 19 and composite filled troughs 27.

The advantage of employin wall sections substantially as high as it is esired to .have the distance between floors of the building and as wide as the distance between floor beam-supporting columns manifestly lies with the great saving in labor cost both by reaIsoili of requiring ,fewer men and less time.
